Directions for use

Our release agent system BF 500 /BF 700 has been tested and

successfully used with this gelcoat. Before using other release agents,

they should be tested for suitability under practical conditions. If

circumstances permit, we recommend post-curing the moulded part for

several hours at 80 °C so that optimal gelcoat properties are achieved.

For more information on working and curing, see the notes in our

Technical Information leaflet, “Working with BÜFA® -Gelcoats”.
